Tragedy Girls (R)

If Scream and Heathers shacked up and had murderous, millennial offspring, it might look a lot like Tragedy Girls. Director Tyler MacIntyre's darkly hilarious slasher flick mashes up the best of the old horror tropes (like machete-wielding murderers) with some new sinister twists. Midwestern high school seniors Sadie (Brianna Hildebrand) and McKayla (Alexandra Shipp) are hunting for viral fame on social media, sharing their lurid accounts of a murder spree. But it's not enough just to chronicle the exploits of a conveniently local serial killer (Kevin Durand) -- they want to be ahead of the game. The two kidnap the slasher in hopes of getting some tips of the trade. When he refuses, Sadie and McKayla aren't afraid to get their hands dirty.

MacIntyre and Chris Lee Hill's screenplay is rife with absurdity, glorious carnage, jet-black humor -- and best of all, a solid relationship at its core. Likes and shares aren't the only drivers for these teens' sociopathy; their shared penchant for the macabre runs deeper. And thanks to Hildebrand and Shipp's undeniable BFF chemistry, these sweet sociopaths really hook you.

The devious duo, despite their best efforts to execute some gruesome murders, end up with victims whose (sometimes slapstick) deaths are ruled accidental ... which doesn't exactly slay on social media. But as these blood-lusting cheerleaders know: Practice makes perfect.
